Different categories can set the delivery time of 1-30 days. Logistics order number: Merchants need to upload a real and valid logistics order number on the platform to ensure that buyers can query the tracking information of the goods online. Collection time: Within 24 hours after the merchant ships (uploads the logistics order number), the logistics order number must have the first valid logistics collection information on the official website of the corresponding logistics company. Product information: Merchants should pack and send the ordered goods according to the order details and the product description on the web page. There should be no inconsistent product information, lack of goods, accessories, or gifts. Empty packages: Merchants shall not send empty packages or other items that are obviously inconsistent with the product description to buyers during the delivery process, or commit other serious fraudulent acts. In addition, the delivery and collection time requirements under different delivery modes are also different, including spot delivery mode, processing and customization delivery mode, and group delivery mode.
